You can't mix tab and spaces for identation. Best practice is to convert all tabs to spaces.
How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don't mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.
Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn't match the following identations!
What helped me... changing sendmail parameters from -bs to -t.
'sendmail' => '/your/sendmail/path -t',
printf("\nmaximum of %d and %d is = %d",a,b,c);
I tried all previously mentioned answers, but in my case I had to manually specify the include path of the iostream file. As I use MinGW the path was:
C:\MinGW\lib\gcc\mingw32\4.8.1\include\c++
You can add the path in Eclipse under: Project > C/C++ General > Paths and Symbols > Includes > Add. I hope that helps
Use:
$ du -ckx <DIR> | grep total | awk '{print $1}'
Where <DIR> is the directory you want to inspect.
The '-c' gives you grand total data which is extracted using the 'grep total' portion of the command, and the count in Kbytes is extracted with the awk command.
The only caveat here is if you have a subdirectory containing the text "total" it will get spit out as well.
Just make sure that you have one root div and put everything inside this root
<div class="root">
<!--and put all child here --!>
<div class='child1'></div>
<div class='child2'></div>
</div>
and so on

is the character entity reference (meant to be easily parseable by humans). 
is the numeric entity reference (meant to be easily parseable by machines).They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.
You can read more about character entity references in the offical W3C documents.
As has been noted, parsing the date and time is only useful if you know the format being used by the current user (eg. MM/dd/yy or dd-MM-yyyy just to name 2). This could be determined, but by the time you do all the stressing and parsing, you will still end up with some situation where there is an unexpected format used, and more tweaks will be be necessary.
You can also use some external program that will return a date slug in your preferred format, but that has disadvantages of needing to distribute the utility program with your script/batch.
there are also batch tricks using the CMOS clock in a pretty raw way, but that is tooo close to bare wires for most people, and also not always the preferred place to retrieve the date/time.
Below is a solution that avoids the above problems. Yes, it introduces some other issues, but for my purposes I found this to be the easiest, clearest, most portable solution for creating a datestamp in .bat files for modern Windows systems. This is just an example, but I think you will see how to modify for other date and/or time formats, etc.
reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM the following may be needed to be sure cache is clear before using the new setting
reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f
this way work properly and I used it in many projects! for example I get data of views the last 30 days:
$viewsData = DB::table('page_views')
->where('page_id', $page->id)
->whereDate('created_at', '>=', now()->subDays(30))
->select(DB::raw('DATE(created_at) as data'), DB::raw('count(*) as views'))
->groupBy('date')
->get();
If you want to get the number of views based on different IPs, you can use the DISTINCT
like below :
$viewsData = DB::table('page_views')
->where('page_id', $page->id)
->whereDate('created_at', '>=', now()->subDays(30))
->select(DB::raw('DATE(created_at) as data'), DB::raw('count(DISTINCT user_ip) as visitors'))
->groupBy('date')
->get();
You can easily customize it by manipulating the columns name
make sure that you are using the same namespace as your pages
May be i did not fully understand the problem, but, centering all view inside a ConstraintLayout seems very simple. This is what I used:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
Last two lines did the trick!
The original answer of ????? ???????? had an issue, so on the last cell collection view was scrolling to the beginning
func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
targetContentOffset.pointee = scrollView.contentOffset
var indexes = yourCollectionView.indexPathsForVisibleItems
indexes.sort()
var index = indexes.first!
// if velocity.x > 0 && (Get the number of items from your data) > index.row + 1 {
if velocity.x > 0 && yourCollectionView.numberOfItems(inSection: 0) > index.row + 1 {
index.row += 1
} else if velocity.x == 0 {
let cell = yourCollectionView.cellForItem(at: index)!
let position = yourCollectionView.contentOffset.x - cell.frame.origin.x
if position > cell.frame.size.width / 2 {
index.row += 1
}
}
yourCollectionView.scrollToItem(at: index, at: .centeredHorizontally, animated: true )
}
The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.
The way you get your original array back is by using Convert.FromBase64String
:
byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);
.....
$("#testID #testID2").removeClass("test2").addClass("test3");
Because you have assigned an id to img too, you can simply do this too:
$("#testID2").removeClass("test2").addClass("test3");
And finally, you can do this too:
$("#testID img").removeClass("test2").addClass("test3");
That's how I am able to do with the help of solution given by @tdammers below. The following line will be placed inside foreach loop.
$array[] = array('power' => trim("Some value"), 'time' => "time here" );
And then encode the array with json encode function
json_encode(array('newvalue'=> $array), 200)
vector<string> split(string str, string token){
vector<string>result;
while(str.size()){
int index = str.find(token);
if(index!=string::npos){
result.push_back(str.substr(0,index));
str = str.substr(index+token.size());
if(str.size()==0)result.push_back(str);
}else{
result.push_back(str);
str = "";
}
}
return result;
}
split("1,2,3",",") ==> ["1","2","3"]
split("1,2,",",") ==> ["1","2",""]
split("1token2token3","token") ==> ["1","2","3"]

I kinda disagree with the accepted answer. Sometimes an application architecture doesn't want you to mess with the array id, or makes it inconvenient. For instance, I use CakePHP quite a lot, and a database query returns the primary key as a value in each record, very similar to the above.
Assuming the array is not stupidly large, I would use array_filter. This will create a copy of the array, minus the records you want to remove, which you can assign back to the original array variable.
Although this may seem inefficient it's actually very much in vogue these days to have variables be immutable, and the fact that most php array functions return a new array rather than futzing with the original implies that PHP kinda wants you to do this too. And the more you work with arrays, and realize how difficult and annoying the unset() function is, this approach makes a lot of sense.
Anyway:
$my_array = array_filter($my_array,
function($el) {
return $el["value"]!="Completed" && $el!["value"]!="Marked as Spam";
});
You can use whatever inclusion logic (eg. your id field) in the embedded function that you want.
Here is a code sample that explains how to get battery information.
To sum it up, a broadcast receiver for the ACTION_BATTERY_CHANGED
intent is set up dynamically, because it can not be received through components declared in manifests, only by explicitly registering for it with Context.registerReceiver()
.
public class Main extends Activity {
private TextView batteryTxt;
private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
@Override
public void onReceive(Context ctxt, Intent intent) {
int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
float batteryPct = level * 100 / (float)scale;
batteryTxt.setText(String.valueOf(batteryPct) + "%");
}
};
@Override
public void onCreate(Bundle b) {
super.onCreate(b);
setContentView(R.layout.main);
batteryTxt = (TextView) this.findViewById(R.id.batteryTxt);
this.registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}
}
Best way to do this is to add a data attribute to the field (textbox) where you want to avoid the cut,copy and paste.
Just create a method for the same which is as follows :-
function ignorePaste() {
$("[data-ignorepaste]").bind("cut copy paste", function (e) {
e.preventDefault(); //prevent the default behaviour
});
};
Then once when you add the above code simply add the data attribute to the field where you want to ignore cut copy paste. in our case your add a data attribute to confirm email text box as below :-
Confirm Email: <input type="textbox" id= "confirmEmail" data-ignorepaste=""/>
Call the method ignorePaste()
So in this way you will be able to use this throughout the application, all you need to do is just add the data attribute where you want to ignore cut copy paste
Mobile Safari (iPhone & iPod Touch) use the tel:

right way is
import datetime
isinstance(x, datetime.date)
When I try this on my machine it works fine. You need to look into why datetime.date
is not a class. Are you perhaps masking it with something else? or not referencing it correctly for your import?
<script language="javascript" type="text/javascript">
function fixedlength(textboxID, keyEvent, maxlength) {

}
else if (textboxID.value.length < maxlength || textboxID.value.length == maxlength) {
textboxID.value = textboxID.value.replace(/[^\d]+/g, '');
return true;
}
else
return false;
}
</script>
<asp:TextBox ID="txtNextVisit" runat="server" MaxLength="2" onblur="return fixedlength(this, event, 2);" onkeypress="return fixedlength(this, event, 2);" onkeyup="return fixedlength(this, event, 2);"></asp:TextBox>
searchfile = open("file.txt", "r")
for line in searchfile:
if "searchphrase" in line: print line
searchfile.close()
To print out multiple lines (in a simple way)
f = open("file.txt", "r")
searchlines = f.readlines()
f.close()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print
The comma in print l,
prevents extra spaces from appearing in the output; the trailing print statement demarcates results from different lines.
Or better yet (stealing back from Mark Ransom):
with open("file.txt", "r") as f:
searchlines = f.readlines()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print

To duplicate a table and its structure without data from a different a database use this. On the new database sql type
CREATE TABLE currentdatabase.tablename LIKE olddatabase.tablename
datetime.datetime.fromtimestamp()
is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp()
expects Unix timestamp, in seconds.
Do it like that:
>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)
and the result is:
>>> date
datetime.datetime(2012, 3, 16, 1, 0)
Does it answer your question?
EDIT: J.F. Sebastian correctly suggested to use true division by 1e3
(float 1000
). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int
when dividing (using /
operator) int
by int
(this is called floor division). By replacing the divisor 1000
(being an int
) with the 1e3
divisor (being representation of 1000
as float) or with float(1000)
(or 1000.
etc.), the division becomes true division. Python 2.x returns float
when dividing int
by float
, float
by int
, float
by float
etc. And when there is some fractional part in the timestamp passed to fromtimestamp()
method, this method's result also contains information about that fractional part (as the number of microseconds).
For those who dont want to use datepicker method
var alldatepicker= $("[class$=hasDatepicker]");
alldatepicker.each(function(){
var value=$(this).val();
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10) {
dd='0'+dd
}
if(mm<10) {
mm='0'+mm
}
today = mm+'/'+dd+'/'+yyyy;
if(value!=''){
if(value>today){
alert("Date cannot be greater than current date");
}
}
});
As dasblinkenlight already answered, the numbers come from the way that floating point numbers are represented in IEEE-754, and Andreas has a nice breakdown of the maths.
However - be careful that the precision of floating point numbers isn't exactly 6 or 15 significant decimal digits as the table suggests, since the precision of IEEE-754 numbers depends on the number of significant binary digits.
float
has 24 significant binary digits - which depending on the number represented translates to 6-8 decimal digits of precision.
double
has 53 significant binary digits, which is approximately 15 decimal digits.
Another answer of mine has further explanation if you're interested.
I'm not expert in T-SQL, but the simpliest way I've already used it's like that:
select char((rand()*25 + 65))+char((rand()*25 + 65))
This generates two char (A-Z, in ascii 65-90).
Just add the following code after the final message you give using PHP code

Another helpful answer. How do I use getConstructor(params).newInstance(args)?
return Class.forName(**complete classname**)
.getConstructor(**here pass parameters passed in constructor**)
.newInstance(**here pass arguments**);
In my case, my class's constructor takes Webdriver as parameter, so used below code:
return Class.forName("com.page.BillablePage")
.getConstructor(WebDriver.class)
.newInstance(this.driver);
Use empty()
. It checks for both empty strings and null.
if (!empty($_POST['user'])) {
// do stuff
}
From the manual:
The following things are considered to be empty:
"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
var $var; (a variable declared, but without a value in a class)
Good news everyone some people! Newer browsers will trigger a window resize event when the zoom is changed.
You can do it with the below code. You first get the data array using dictionary.data and assign it to the data variable. After that you can iterate it using a normal for loop. Each row will be a row object in the array.
var data = dictionary.data;
for (var i in data)
{
var id = data[i].id;
var name = data[i].name;
}
You can follow similar approach to iterate the image array.
You can do it like this:
SELECT * FROM (SELECT your_table.your_field, versions_starttime
FROM your_table
VERSIONS BETWEEN TIMESTAMP MINVALUE AND MAXVALUE)
WHERE ROWNUM = 1;
Or:
SELECT your_field,ora_rowscn,scn_to_timestamp(ora_rowscn) from your_table WHERE ROWNUM = 1;
<meta http-equiv="X-UA-Compatible" content="IE=8" />
should force your page to render in IE8 standards. The user may add the site to compatibility list but this tag will take precedence.
A quick way to check would be to load the page and type the following the address bar :
javascript:alert(navigator.userAgent)
If you see IE7 in the string, it is loading in compatibility mode, otherwise not.
The BigDecimal can not be a double. you can use Int number. if you want to display exactly own number, you can use the String constructor of BigDecimal .
like this:
BigDecimal bd1 = new BigDecimal("10.0001");
now, you can display bd1 as 10.0001
So simple. GOOD LUCK.
You can't run PHP
in an html page ending with .html
. Unless the page is actually PHP and the extension was changed with .htaccess
from .php
to .html
What you mean is:
index.html
<html>
...
<?php echo "Hello world";?> //This is impossible
index.php //The file extension can be changed using htaccess, ex: its type stays php but will be visible to visitors as index.html
<?php echo "Hello world";?>
?max
shows you that there is an extra parameter na.rm
that you can set to TRUE
.
Apart from that, if you really want to remove the NA
s, just use something like:
myvec[!is.na(myvec)]
Try this:
Update MasterTbl Set
TotalX = Sum(D.X),
TotalY = Sum(D.Y),
TotalZ = Sum(D.Z)
From MasterTbl M Join DetailTbl D
On D.MasterID = M.MasterID
Depending on which database you are using, if that doesn't work, then try this (this is non-standard SQL but legal in SQL Server):
Update M Set
TotalX = Sum(D.X),
TotalY = Sum(D.Y),
TotalZ = Sum(D.Z)
From MasterTbl M Join DetailTbl D
On D.MasterID = M.MasterID
This would be more performant than trimming the whole string, since you only need to check for at least a single non-space character existing
// Strempty checks whether string contains only whitespace or not
func Strempty(s string) bool {
if len(s) == 0 {
return true
}
r := []rune(s)
l := len(r)
for l > 0 {
l--
if !unicode.IsSpace(r[l]) {
return false
}
}
return true
}

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.
src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?
Blob URLs can only be generated internally by the browser. URL.createObjectURL()
will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL()
. These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).
What is blob url?
Why it is used?
Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.
For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.
It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.
Can i make my own blob url on a server?
No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.
if you have then Additional detail
You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL()
to generate a local URL for it:
var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
url = URL.createObjectURL(blob),
img = new Image();
img.onload = function() {
URL.revokeObjectURL(this.src); // clean-up memory
document.body.appendChild(this); // add image to DOM
}
img.src = url; // can now "stream" the bytes
Note that URL
may be prefixed in webkit-browsers, so use:
var url = (URL || webkitURL).createObjectURL(...);
Simply switch to the Design View, and locate the concerned widget. Grab the one of the dots on the boundary of the widget and join it to an appropriate edge of the screen (or to a dot on some other widget).
For instance, if the widget is a toolbar, just grab the top-most dot and join it to the top-most edge of the phone screen as shown in the image.

What's the first part of your Subversion repository URL?
I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.
If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.
The only way around that is to log into a local machine over the VPN, and then do everything from that system.
For a short answer you should use np.save
and np.load
. The advantages of these is that they are made by developers of the numpy library and they already work (plus are likely already optimized nicely) e.g.
import numpy as np
from pathlib import Path
path = Path('~/data/tmp/').expanduser()
path.mkdir(parents=True, exist_ok=True)
lb,ub = -1,1
num_samples = 5
x = np.random.uniform(low=lb,high=ub,size=(1,num_samples))
y = x**2 + x + 2
np.save(path/'x', x)
np.save(path/'y', y)
x_loaded = np.load(path/'x.npy')
y_load = np.load(path/'y.npy')
print(x is x_loaded) # False
print(x == x_loaded) # [[ True True True True True]]
Expanded answer:
In the end it really depends in your needs because you can also save it human readable format (see this Dump a NumPy array into a csv file) or even with other libraries if your files are extremely large (see this best way to preserve numpy arrays on disk for an expanded discussion).
However, (making an expansion since you use the word "properly" in your question) I still think using the numpy function out of the box (and most code!) most likely satisfy most user needs. The most important reason is that it already works. Trying to use something else for any other reason might take you on an unexpectedly LONG rabbit hole to figure out why it doesn't work and force it work.
Take for example trying to save it with pickle. I tried that just for fun and it took me at least 30 minutes to realize that pickle wouldn't save my stuff unless I opened & read the file in bytes mode with wb
. Took time to google, try thing, understand the error message etc... Small detail but the fact that it already required me to open a file complicated things in unexpected ways. To add that it required me to re-read this (which btw is sort of confusing) Difference between modes a, a+, w, w+, and r+ in built-in open function?.
So if there is an interface that meets your needs use it unless you have a (very) good reason (e.g. compatibility with matlab or for some reason your really want to read the file and printing in python really doesn't meet your needs, which might be questionable). Furthermore, most likely if you need to optimize it you'll find out later down the line (rather than spend ages debugging useless stuff like opening a simple numpy file).
So use the interface/numpy provide. It might not be perfect it's most likely fine, especially for a library that's been around as long as numpy.
I already spent the saving and loading data with numpy in a bunch of way so have fun with it, hope it helps!

Some comments on what I learned:
np.save
as expected, this already compresses it well (see https://stackoverflow.com/a/55750128/1601580), works out of the box without any file opening. Clean. Easy. Efficient. Use it.np.savez
uses a uncompressed format (see docs) Save several arrays into a single file in uncompressed
.npz format.
If you decide to use this (you were warned to go away from the standard solution so expect bugs!) you might discover that you need to use argument names to save it, unless you want to use the default names. So don't use this if the first already works (or any works use that!)hdf5
for large files. Cool! https://stackoverflow.com/a/9619713/1601580Note this is not an exhaustive answer. But for other resources check this:
np.save
): Save Numpy Array using PickleThe accepted answer is out of date. I found a better answer: Use Import Data-tier Application

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:
x = ["0", "1", "2"]
y = int(x[0]) #accessing the zeroth element
If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:
x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)
If your list elements are not strings, you'll have to convert them to strings before using str.join
:
x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)
Also, as stated above, make sure that you're not returning a nested list.
The above one with JQuery is the easiest and mostly used way. However you can use pure javascript but try to define this script in the head so that it is read at the beginning. What you are looking for is window.onload
event.
Below is a simple script that I created to run a counter. The counter then stops after 10 iterations
window.onload=function()
{
var counter = 0;
var interval1 = setInterval(function()
{
document.getElementById("div1").textContent=counter;
counter++;
if(counter==10)
{
clearInterval(interval1);
}
},1000);
}
Probably you don't have the service in your manifest, or it does not have an <intent-filter>
that matches your action. Examining LogCat (via adb logcat
, DDMS, or the DDMS perspective in Eclipse) should turn up some warnings that may help.
More likely, you should start the service via:
startService(new Intent(this, UpdaterServiceManager.class));
You should do it with getActivity().startActivity(myIntent)
I think the hash-value is only used client-side, so you can't get it with php.
you could redirect it with javascript to php though.
A few examples follow, going from basic through to adding transformations after the request and/or error handling:
// Implementation code where T is the returned data shape
function api<T>(url: string): Promise<T> {
return fetch(url)
.then(response => {
if (!response.ok) {
throw new Error(response.statusText)
}
return response.json<T>()
})
}
// Consumer
api<{ title: string; message: string }>('v1/posts/1')
.then(({ title, message }) => {
console.log(title, message)
})
.catch(error => {
/* show error message */
})
Often you may need to do some tweaks to the data before its passed to the consumer, for example, unwrapping a top level data attribute. This is straight forward:
function api<T>(url: string): Promise<T> {
return fetch(url)
.then(response => {
if (!response.ok) {
throw new Error(response.statusText)
}
return response.json<{ data: T }>()
})
.then(data => { /* <-- data inferred as { data: T }*/
return data.data
})
}
// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
.then(({ title, message }) => {
console.log(title, message)
})
.catch(error => {
/* show error message */
})
I'd argue that you shouldn't be directly error catching directly within this service, instead, just allowing it to bubble, but if you need to, you can do the following:
function api<T>(url: string): Promise<T> {
return fetch(url)
.then(response => {
if (!response.ok) {
throw new Error(response.statusText)
}
return response.json<{ data: T }>()
})
.then(data => {
return data.data
})
.catch((error: Error) => {
externalErrorLogging.error(error) /* <-- made up logging service */
throw error /* <-- rethrow the error so consumer can still catch it */
})
}
// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
.then(({ title, message }) => {
console.log(title, message)
})
.catch(error => {
/* show error message */
})
There has been some changes since writing this answer a while ago. As mentioned in the comments, response.json<T>
is no longer valid. Not sure, couldn't find where it was removed.
For later releases, you can do:
// Standard variation
function api<T>(url: string): Promise<T> {
return fetch(url)
.then(response => {
if (!response.ok) {
throw new Error(response.statusText)
}
return response.json() as Promise<T>
})
}
// For the "unwrapping" variation
function api<T>(url: string): Promise<T> {
return fetch(url)
.then(response => {
if (!response.ok) {
throw new Error(response.statusText)
}
return response.json() as Promise<{ data: T }>
})
.then(data => {
return data.data
})
}
Use the $_SERVER['HTTP_REFERER']
header, but bear in mind anybody can spoof it at anytime regardless of whether they clicked on a link.
Adding on to the other answers using requests:
# download from web
import requests
url = 'http://mlg.ucd.ie/files/datasets/bbc.zip'
content = requests.get(url)
# unzip the content
from io import BytesIO
from zipfile import ZipFile
f = ZipFile(BytesIO(content.content))
print(f.namelist())
# outputs ['bbc.classes', 'bbc.docs', 'bbc.mtx', 'bbc.terms']
Use help(f) to get more functions details for e.g. extractall() which extracts the contents in zip file which later can be used with with open.
I found this to work best
var data = [
{ label: "Choice 1", value: "choice_1" },
{ label: "Choice 2", value: "choice_2" },
{ label: "Choice 3", value: "choice_3" }
];
$("#example")
.autocomplete({
source: data,
minLength: 0
})
.focus(function() {
$(this).autocomplete('search', $(this).val())
});
It searches the labels and places the value into the element $(#example)
Looking at the sample I guess you mean that a string array is actually an array of HEX representation of bytes, don't you?
If yes, then for each string item I would do the following:
build a byte value, where first char is higher bits and second char is lower ones. E.g.
int byteVal = (firstCharNumber << 4) | secondCharNumber;
I had this problem with a ComboBox displaying a list of colors ( List<Brush> ).
Selecting a color was possible but it wasnt displayed when the selection closed (although the property was changed!)
The fix was overwriting the Equals(object obj) method for the type selected in the ComboBox (Brush), which wasnt simple because Brush is sealed. So i wrote a class EqualityBrush containing a Brush and implementing Equals:
public class EqualityBrush
{
public SolidColorBrush Brush { get; set; }
public override bool Equals(object o)
{
if (o is EqualityBrush)
{
SolidColorBrush b = ((EqualityBrush)o).Brush;
return b.Color.R == this.Brush.Color.R && b.Color.G == this.Brush.Color.G && b.Color.B == this.Brush.Color.B;
}
else
return false;
}
}
Using a List of my new EqualityBrush class instead of normal Brush class fixed the problem!
My Combobox XAML looks like this:
<ComboBox ItemsSource="{Binding BuerkertBrushes}" SelectedItem="{Binding Brush, Mode=TwoWay}" Width="40">
<ComboBox.Resources>
<DataTemplate DataType="{x:Type tree:EqualityBrush}">
<Rectangle Width="20" Height="12" Fill="{Binding Brush}"/>
</DataTemplate>
</ComboBox.Resources>
</ComboBox>
Remember that my "Brush"-Property in the ViewModel now has to be of Type EqualityBrush!
Quite simple, quite permissive. It will have false positives like -notvalid.at-all, but it won't have false negatives.
/^([0-9a-z-]+\.?)+$/i
It makes sure it has a sequence of letters numbers and dashes that could end with a dot, and following it, any number of those kind of sequences.
The things I like about this regexp: it's short (maybe the shortest here), easily understandable, and good enough for validating user input errors in the client side.
Updated Answer for Changed Documentation
The information is now spread across several guides in the documentation. Here's a list of required reading:
The answer to this question now depends entirely on whether you're using an ARC-managed application (the modern default for new projects) or forcing manual memory management.
Assign vs. Weak - Use assign to set a property's pointer to the address of the object without retaining it or otherwise curating it; use weak to have the property point to nil automatically if the object assigned to it is deallocated. In most cases you'll want to use weak so you're not trying to access a deallocated object (illegal access of a memory address - "EXC_BAD_ACCESS
") if you don't perform proper cleanup.
Retain vs. Copy - Declared properties use retain by default (so you can simply omit it altogether) and will manage the object's reference count automatically whether another object is assigned to the property or it's set to nil; Use copy to automatically send the newly-assigned object a -copy
message (which will create a copy of the passed object and assign that copy to the property instead - useful (even required) in some situations where the assigned object might be modified after being set as a property of some other object (which would mean that modification/mutation would apply to the property as well).
I think you can use hash of RSVP.
Something like as below :
const mainPromise = () => {
const promise1 = new Promise((resolve, reject) => {
setTimeout(() => {
console.log('first promise is completed');
resolve({data: '123'});
}, 2000);
});
const promise2 = new Promise((resolve, reject) => {
setTimeout(() => {
console.log('second promise is completed');
resolve({data: '456'});
}, 2000);
});
return new RSVP.hash({
prom1: promise1,
prom2: promise2
});
};
mainPromise()
.then(data => {
console.log(data.prom1);
console.log(data.prom2);
});
Simply type conda update pandas
in your preferred shell (on Windows, use cmd; if Anaconda is not added to your PATH use the Anaconda prompt). You can of course use Eclipse together with Anaconda, but you need to specify the Python-Path (the one in the Anaconda-Directory).
See this document for a detailed instruction.
For MySql you can do something like the following:
select OrderNO, PartCode, Quantity from table a
join (select ID, MAX(DateEntered) from table group by OrderNO) b on a.ID = b.ID
If you know in advance the position in the file (rather the line number), you can use file.seek() to go to that position.
Edit: you can use the linecache.getline(filename, lineno) function, which will return the contents of the line lineno, but only after reading the entire file into memory. Good if you're randomly accessing lines from within the file (as python itself might want to do to print a traceback) but not good for a 15MB file.
the_input = raw_input("Enter input: ")
And that's it.
Moreover, if you want to make a list of inputs, you can do something like:
a = []
for x in xrange(1,10):
a.append(raw_input("Enter Data: "))
In that case, you'll be asked for data 10 times to store 9 items in a list.
Output:
Enter data: 2
Enter data: 3
Enter data: 4
Enter data: 5
Enter data: 7
Enter data: 3
Enter data: 8
Enter data: 22
Enter data: 5
>>> a
['2', '3', '4', '5', '7', '3', '8', '22', '5']
You can search that list the fundamental way with something like (after making that list):
if '2' in a:
print "Found"
else: print "Not found."
You can replace '2' with "raw_input()" like this:
if raw_input("Search for: ") in a:
print "Found"
else:
print "Not found"
If you want to take the input from a file you feed through commandline (which is normally what you need when doing code problems for competitions, like Google Code Jam or the ACM/IBM ICPC):
example.py
while(True):
line = raw_input()
print "input data: %s" % line
In command line interface:
example.py < input.txt
Hope that helps.
In regards to @Anthonyeef great answer, here is a sample code in Java:
private boolean shouldShowFragmentInOnResume;
private void someMethodThatShowsTheFragment() {
if (this.getLifecycle().getCurrentState().isAtLeast(Lifecycle.State.RESUMED)) {
showFragment();
} else {
shouldShowFragmentInOnResume = true;
}
}
private void showFragment() {
//Your code here
}
@Override
protected void onResume() {
super.onResume();
if (shouldShowFragmentInOnResume) {
shouldShowFragmentInOnResume = false;
showFragment();
}
}
color=(200, 100, 255) # sample of a color
img = np.full((100, 100, 3), color, np.uint8)
Void is an incomplete type which, by definition, can't be an lvalue. That means it can't get assigned a value.
So it also can't hold any value.
Programmatically using D3:
body = d3.select('body')
svg = body.append('svg').attr('height', 600).attr('width', 200)
rect = svg.append('rect').transition().duration(500).attr('width', 150)
.attr('height', 100)
.attr('x', 40)
.attr('y', 100)
.style('fill', 'white')
.attr('stroke', 'black')
text = svg.append('text').text('This is some information about whatever')
.attr('x', 50)
.attr('y', 150)
.attr('fill', 'black')
This seems to work easily.

My favorite slow sorting algorithm is the stooge sort:
void stooges(long *begin, long *end) {
if( (end-begin) <= 1 ) return;
if( begin[0] < end[-1] ) swap(begin, end-1);
if( (end-begin) > 1 ) {
int one_third = (end-begin)/3;
stooges(begin, end-one_third);
stooges(begin+one_third, end);
stooges(begin, end-one_third);
}
}
The worst case complexity is O(n^(log(3) / log(1.5))) = O(n^2.7095...)
.
Another slow sorting algorithm is actually named slowsort!
void slow(long *start, long *end) {
if( (end-start) <= 1 ) return;
long *middle = start + (end-start)/2;
slow(start, middle);
slow(middle, end);
if( middle[-1] > end[-1] ) swap(middle-1, end-1);
slow(start, end-1);
}
This one takes O(n ^ (log n))
in the best case... even slower than stoogesort.
No, IIRC there is no getopt() on Windows.
Boost, however, has the program_options library... which works okay. It will seem like overkill at first, but it isn't terrible, especially considering it can handle setting program options in configuration files and environment variables in addition to command line options.
Range.Rows, Range.Columns and Range.Cells are Excel.Range objects, according to the VBA Type() functions:
?TypeName(Selection.rows) RangeHowever, that's not the whole story: those returned objects are extended types that inherit every property and method from Excel::Range - but .Columns and .Rows have a special For... Each iterator, and a special .Count property that aren't quite the same as the parent Range object's iterator and count.
So .Cells is iterated and counted as a collection of single-cell ranges, just like the default iterator of the parent range.
But .Columns is iterated and counted as a collection of vertical subranges, each of them a single column wide;
...And .Rows is iterated and counted as a collection of horizontal subranges, each of them a single row high.
The easiest way to understand this is to step through this code and watch what's selected:
Public Sub Test()Enjoy. And try it with a couple of merged cells in there, just to see how odd merged ranges can be.
Dim SubRange As Range Dim ParentRange As Range
Set ParentRange = ActiveSheet.Range("B2:E5")
For Each SubRange In ParentRange.Cells SubRange.Select Next
For Each SubRange In ParentRange.Rows SubRange.Select Next
For Each SubRange In ParentRange.Columns SubRange.Select Next
For Each SubRange In ParentRange SubRange.Select Next
End Sub
Very simple you have to just put

In your controller use:
var path = HttpContext.Server.MapPath("~/Data/data.html");
This allows you to test the controller with Moq like so:
var queryString = new NameValueCollection();
var mockRequest = new Mock<HttpRequestBase>();
mockRequest.Setup(r => r.QueryString).Returns(queryString);
var mockHttpContext = new Mock<HttpContextBase>();
mockHttpContext.Setup(c => c.Request).Returns(mockRequest.Object);
var server = new Mock<HttpServerUtilityBase>();
server.Setup(m => m.MapPath("~/Data/data.html")).Returns("path/to/test/data");
mockHttpContext.Setup(m => m.Server).Returns(server.Object);
var mockControllerContext = new Mock<ControllerContext>();
mockControllerContext.Setup(c => c.HttpContext).Returns(mockHttpContext.Object);
var controller = new MyTestController();
controller.ControllerContext = mockControllerContext.Object;
For you the get the most alike representation of your original string I recommend the unidecode module:
from unidecode import unidecode
def remove_non_ascii(text):
return unidecode(unicode(text, encoding = "utf-8"))
Then you can use it in a string:
remove_non_ascii("Ceñía")

The Date class already implements Comparator interface. Assuming you have the class below:
public class A {
private Date dateTime;
public Date getDateTime() {
return dateTime;
}
.... other variables
}
And let's say you have a list of A objects as List<A> aList
, you can easily sort it with Java 8's stream API (snippet below):
import java.util.Comparator;
import java.util.stream.Collectors;
...
aList = aList.stream()
.sorted(Comparator.comparing(A::getDateTime))
.collect(Collectors.toList())
I got this to work by Populating a SelectListItem, converting to an List, and adding a value at index 0.
List<SelectListItem> items = new SelectList(CurrentViewSetups, "SetupId", "SetupName", setupid).ToList();
items.Insert(0, (new SelectListItem { Text = "[None]", Value = "0" }));
ViewData["SetupsSelectList"] = items;

Zend Framework can load and edit existing PDF files. I think it supports revisions too.
I use it to create docs in a project, and it works great. Never edited one though.
Check out the doc here
Well,
$xml = "l
vv";
Works.
You can also use the following:
$xml = "l\nvv";
or
$xml = <<<XML
l
vv
XML;
You can concatenate strings using the .=
operator.
$str = "Hello";
$str .= " World";
echo $str; //Will echo out "Hello World";
In general, don't do this:
pip install package
because, as you have correctly noticed, it's not clear what Python version you're installing package
for.
Instead, if you want to install package
for Python 3.7, do this:
python3.7 -m pip install package
Replace package
with the name of whatever you're trying to install.
Took me a surprisingly long time to figure it out, too. The docs about it are here.
Your other option is to set up a virtual environment. Once your virtual environment is active, executable names like python
and pip
will point to the correct ones.
A regex is good for matching the general format but I think you should move parsing to the Date class, e.g.:
function parseDate(str) {
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/);
return (m) ? new Date(m[3], m[2]-1, m[1]) : null;
}
Now you can use this function to check for valid dates; however, if you need to actually validate without rolling (e.g. "31/2/2010" doesn't automatically roll to "3/3/2010") then you've got another problem.
[Edit] If you also want to validate without rolling then you could add a check to compare against the original string to make sure it is the same date:
function parseDate(str) {
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
, d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
, nonRolling = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
return (nonRolling) ? d : null;
}
[Edit2] If you want to match against zero-padded dates (e.g. "08/08/2013") then you could do something like this:
function parseDate(str) {
function pad(x){return (((''+x).length==2) ? '' : '0') + x; }
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
, d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
, matchesPadded = (d&&(str==[pad(d.getDate()),pad(d.getMonth()+1),d.getFullYear()].join('/')))
, matchesNonPadded = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
return (matchesPadded || matchesNonPadded) ? d : null;
}
However, it will still fail for inconsistently padded dates (e.g. "8/08/2013").
There's a super small section in the DOCs that shows how to find/find_all direct children.
https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-recursive-argument
In your case as you want link1 which is first direct child:
# for only first direct child
soup.find("li", { "class" : "test" }).find("a", recursive=False)
If you want all direct children:
# for all direct children
soup.find("li", { "class" : "test" }).findAll("a", recursive=False)
Enumerating the possibilities allowed by the grammar:
>>> seq[:] # [seq[0], seq[1], ..., seq[-1] ]
>>> seq[low:] # [seq[low], seq[low+1], ..., seq[-1] ]
>>> seq[:high] # [seq[0], seq[1], ..., seq[high-1]]
>>> seq[low:high] # [seq[low], seq[low+1], ..., seq[high-1]]
>>> seq[::stride] # [seq[0], seq[stride], ..., seq[-1] ]
>>> seq[low::stride] # [seq[low], seq[low+stride], ..., seq[-1] ]
>>> seq[:high:stride] # [seq[0], seq[stride], ..., seq[high-1]]
>>> seq[low:high:stride] # [seq[low], seq[low+stride], ..., seq[high-1]]
Of course, if (high-low)%stride != 0
, then the end point will be a little lower than high-1
.
If stride
is negative, the ordering is changed a bit since we're counting down:
>>> seq[::-stride] # [seq[-1], seq[-1-stride], ..., seq[0] ]
>>> seq[high::-stride] # [seq[high], seq[high-stride], ..., seq[0] ]
>>> seq[:low:-stride] # [seq[-1], seq[-1-stride], ..., seq[low+1]]
>>> seq[high:low:-stride] # [seq[high], seq[high-stride], ..., seq[low+1]]
Extended slicing (with commas and ellipses) are mostly used only by special data structures (like NumPy); the basic sequences don't support them.
>>> class slicee:
... def __getitem__(self, item):
... return repr(item)
...
>>> slicee()[0, 1:2, ::5, ...]
'(0, slice(1, 2, None), slice(None, None, 5), Ellipsis)'
I had the exact same problem, this - "meta http-equiv="X-UA-Compatible" content="IE=7">" works great in IE8 and IE9, but not in IE10. There is a bug in the server browser definition files that shipped with .NET 2.0 and .NET 4, namely that they contain definitions for a certain range of browser versions. But the versions for some browsers (like IE 10) aren't within those ranges any more. Therefore, ASP.NET sees them as unknown browsers and defaults to a down-level definition, which has certain inconveniences, like that it does not support features like JavaScript.
My thanks to Scott Hanselman for this fix.
Here is the link -
This MS KP fix just adds missing files to the asp.net on your server. I installed it and rebooted my server and it now works perfectly. I would have thought that MS would have given this fix a wider distribution.

I was with Angular 8 and the only thing which worked for me was this:

.set('Api-Key', 'xxx');
return headers;
}
I wanted to solve this simple solution in a straightforward way of writing, with a little bit of a pain of computational expenses... but isn't it a trivial solution with a minimum variable definition, is it?

if(_.every(out, outobj => !_.isEqual(obj, outobj))) out.push(obj)
})

I was facing same issue and got the error while uploading apk to Google play. I used ads in my app, and I was not even mentioned READ_PHONE_STATE permission in my manifest file. but yet I got this error. Then I change dependencies for ads in build.gradle file. and then it solved my issue. They solved this issue in 12.0.1.
compile 'com.google.android.gms:play-services-ads:12.0.1'
When you get this error, it means that code you are using makes a reference to an type that is in an assembly, but the assembly is not part of your project so it can't use it.
Deleting Project.Rights.dll is the opposite of what you want. You need to make sure your project can reference the assembly. So it must either be placed in the Global Assembly Cache or your web application's ~/Bin directory.
Edit-If you don't want to use the assembly, then deleting it is not the proper solution either. Instead, you must remove all references to it in your code. Since the assembly isn't directly needed by code you've written, but instead by something else you're referencing, you'll have to replace that referenced assembly with something that doesn't have Project.Rights.dll as a dependency.

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.
As I mentioned in the comment, having to use the dot()
function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.
Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @
infix-operator for matrix multiplication, thanks to pep 465.
Edit: Regarding your comment:
Yes. The whole of numpy is based on arrays.
Yes. linalg.norm(v)
is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.
To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.
An example in ipython:
In [1]: import math
In [2]: import numpy as np
In [3]: a = np.array([4,2,7])
In [4]: np.linalg.norm(a)
Out[4]: 8.3066238629180749
In [5]: math.sqrt(sum([n**2 for n in a]))
Out[5]: 8.306623862918075
In [6]: b = a/np.linalg.norm(a)
In [7]: np.linalg.norm(b)
Out[7]: 1.0
Note that In [5]
is an alternative way to calculate the length. In [6]
shows normalizing the vector.
To activate debug mode in flask you simply type set FLASK_DEBUG=1
on your CMD
for windows and export FLASK_DEBUG=1
on Linux termial then restart your app and you are good to go!!
If you haven't commit the local changes yet since the last pull/clone, you can use:
git checkout *
git pull
checkout
will clear your local changes with the last local commit, and
pull
will sincronize it to the remote repository
If you're looking to get promise in resource call, you should use
Regions.query().$q.then(function(){ .... })
Update : the promise syntax is changed in current versions which reads
Regions.query().$promise.then(function(){ ..... })
Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.
No one has mentioned it, but JavaFX does not compile or run on certain architectures deemed "servers" by Oracle (e.g. Solaris), because of the missing "jfxrt.jar" support. Stick with SWT, until further notice.
This is another way:
1.Create a BaseFragment like this:
public abstract class BaseFragment extends Fragment implements OnClickListener
2.Use
public class FragmentA extends BaseFragment
instead of
public class FragmentA extends Fragment
3.In your activity:
public class MainActivity extends ActionBarActivity implements OnClickListener
and
BaseFragment fragment = new FragmentA;
public void onClick(View v){
fragment.onClick(v);
}
Hope it helps.
The idiomatic way to do this in Python is to use rstrip('\n'):
for line in open('myfile.txt'): # opened in text-mode; all EOLs are converted to '\n'
line = line.rstrip('\n')
process(line)
Each of the other alternatives has a gotcha:
For me this issue only occurred on Android < 4.0
The combination of parameters I used were:
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
The maxLines count seemed to be the random final piece that made my TextView wrap.
Just test if the array is empty.

We can run Linux containers on Windows. Docker for Windows uses Hyper-v based Linux-Kit or WSL2 as backend to facilitate Linux containers.
If any Linux distribution having this kind of setup, we can run Windows containers. Docker for Linux supports only Linux containers.
See the relevel()
function. Here is an example:
set.seed(123)
x <- rnorm(100)
DF <- data.frame(x = x,
y = 4 + (1.5*x) + rnorm(100, sd = 2),
b = gl(5, 20))
head(DF)
str(DF)
m1 <- lm(y ~ x + b, data = DF)
summary(m1)
Now alter the factor b
in DF
by use of the relevel()
function:
DF <- within(DF, b <- relevel(b, ref = 3))
m2 <- lm(y ~ x + b, data = DF)
summary(m2)
The models have estimated different reference levels.

The 60 you're passing is just the initial capacity for internal storage. It's a hint on how big you think it might be, yet of course it's not limited by that. If you need to preset values you'll have to set them yourself, e.g.:
for (int i = 0; i < 60; i++) {
list.add(0);
}
You’re looking for urllib.parse.urlencode

# Returns: 'username=administrator&password=xyz'
I have not found a satisfying answer for this question, i.e how to load edit, run and save. Overwriting either using %%writefile
or %save -f
doesn't work well if you want to show incremental changes in git. It would look like you delete all the lines in filename.py
and add all new lines, even though you just edit 1 line.
You can perform inheritance in enum, however it's limited to following types only . int, uint, byte, sbyte, short, ushort, long, ulong
E.g.
public enum Car:int{
Toyota,
Benz,
}
Lets consider you have a class name named Products and you have a IsActive field. just you need a create constructor :
Public class Products
{
public Products()
{
IsActive = true;
}
public string Field1 { get; set; }
public string Field2 { get; set; }
public bool IsActive { get; set; }
}
Then your IsActive default value is True!
Edite :
if you want to do this with SQL use this command :
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Blog>()
.Property(b => b.IsActive)
.HasDefaultValueSql("true");
}
It is simple, as a java, Android also supporting singleton. -
Singleton is a part of Gang of Four design pattern and it is categorized under creational design patterns.
-> Static member : This contains the instance of the singleton class.
-> Private constructor : This will prevent anybody else to instantiate the Singleton class.
-> Static public method : This provides the global point of access to the Singleton object and returns the instance to the client calling class.
use getInstance() of Singleton class
public class Logger{
private static Logger objLogger;
private Logger(){
//ToDo here
}
public static Logger getInstance()
{
if (objLogger == null)
{
objLogger = new Logger();
}
return objLogger;
}
}
while use singleton -
Logger.getInstance();
LTRIM(RTRIM(FCT_TYP_CD)) & ') AND (' & LTRIM(RTRIM(DEP_TYP_ID)) & ')'
I think you're missing a )
on both of the trims. Some SQL versions support just TRIM which does both L and R trims...
If the answer from falsetru didn't work you could also try:
>>> b'a string'.decode('utf-8')
'a string'
I had a similar issue, but the reason that %ANT_HOME% wasn't resolving is that I had added it as a USER variable, not a SYSTEM one. Sorted now, thanks to this post.

If array
is null
, trying to derefrence array.Length
will throw a NullReferenceException
. If your code considers null
to be an invalid value for array
, you should reject it and blame the caller. One such pattern is to throw ArgumentNullException
:
void MyMethod(string[] array)
{
if (array == null) throw new ArgumentNullException(nameof(array));
if (array.Length > 0)
{
// Do something with array…
}
}
If you want to accept a null
array as an indication to not do something or as an optional parameter, you may simply not access it if it is null:
void MyMethod(string[] array)
{
if (array != null)
{
// Do something with array here…
}
}
If you want to avoid touching array
when it is either null
or has zero length, then you can check for both at the same time with C#-6’s null coalescing operator.
void MyMethod(string[] array)
{
if (array?.Length > 0)
{
// Do something with array…
}
}
It seems strange that you are treating the empty array as a special case. In many cases, if you, e.g., would just loop over the array anyway, there’s no need to treat the empty array as a special case. foreach (var elem in array) {«body»}
will simply never execute «body»
when array.Length
is 0
. If you are treating array == null || array.Length == 0
specially to, e.g., improve performance, you might consider leaving a comment for posterity. Otherwise, the check for Length == 0
appears superfluous.
Superfluous code makes understanding a program harder because people reading the code likely assume that each line is necessary to solve some problem or achieve correctness. If you include unnecessary code, the readers are going to spend forever trying to figure out why that line is or was necessary before deleting it ;-).
What am I doing incorrectly?
You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.
How can I receive a json object in the controller?
View:
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>
var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });
<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>
Controller:
public void PostRawJson(string json)
{
var order = System.Web.Helpers.Json.Decode(json);
var orderDate = order.OrderDate;
var secondOrderId = order.Item[1].Id;
}
If you dont have an entry point defined in your manifest invoking java -jar foo.jar
will not work.
Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:
java -cp foo.jar full.package.name.ClassName
See also instructions on how to create a manifest with an entry point: https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html
I'd consider also Apache Thrift http://thrift.apache.org/
It can bridge between several programming languages, is highly efficient and has support for async or sync calls. See full features here http://thrift.apache.org/docs/features/
The multi language can be useful for future plans, for example if you later want to do part of the computational task in C++ it's very easy to do add it to the mix using Thrift.

Elaborating on yasaluyari
's answer I would stick with something like this:
We can just modify our mysql_query as follows:
function mysql_catchquery($query,$emsg='Error submitting the query'){
if ($result=mysql_query($query)) return $result;
else throw new Exception($emsg);
}
Now we can simply use it like this, some good example:
try {
mysql_catchquery('CREATE TEMPORARY TABLE a (ID int(6))');
mysql_catchquery('insert into a values(666),(418),(93)');
mysql_catchquery('insert into b(ID, name) select a.ID, c.name from a join c on a.ID=c.ID');
$result=mysql_catchquery('select * from d where ID=7777777');
while ($tmp=mysql_fetch_assoc($result)) { ... }
} catch (Exception $e) {
echo $e->getMessage();
}
Note how beautiful it is. Whenever any of the qq fails we gtfo with our errors. And you can also note that we don't need now to store the state of the writing queries into a $result
variable for verification, because our function now handles it by itself. And the same way it handles the selects, it just assigns the result to a variable as does the normal function, yet handles the errors within itself.
Also note, we don't need to show the actual errors since they bear huge security risk, especially so with this outdated extension. That is why our default will be just fine most of the time. Yet, if we do want to notify the user for some particular query error, we can always pass the second parameter to display our custom error message.
I faced the same error and in my case, I change the Server Port Number to 3308 where previously it was 3306. This connect my project to the MySQL database.
Here we have to change the connection code also.
Class.forName("com.mysql.cj.jdbc.Driver");
cn=(java.sql.Connection)DriverManager.getConnection("jdbc:mysql://localhost:3308/test2?zeroDateTimeBehavior=convertToNull","root","");
Changing the port number in the connection code is also necessary as localhost:3308
to resolved the error.
Do you mean shapefile as in an Esri shapefile? Either way, you should be able to perform the conversion using ogr2ogr, which is available in the GDAL packages. You need the .shp
file and ideally the corresponding .dbf
file (which will provide contextual information).
Also, consider using a tool like MapShaper to reduce the complexity of your shapefiles before transforming them into KML; you'll reduce filesize substantially depending on how much detail you need.
Here you go...
- (NSString *)removeEndSpaceFrom:(NSString *)strtoremove{
NSUInteger location = 0;
unichar charBuffer[[strtoremove length]];
[strtoremove getCharacters:charBuffer];
int i = 0;
for(i = [strtoremove length]; i >0; i--) {
NSCharacterSet* charSet = [NSCharacterSet whitespaceCharacterSet];
if(![charSet characterIsMember:charBuffer[i - 1]]) {
break;
}
}
return [strtoremove substringWithRange:NSMakeRange(location, i - location)];
}
So now just call it. Supposing you have a string that has spaces on the front and spaces on the end and you just want to remove the spaces on the end, you can call it like this:
NSString *oneTwoThree = @" TestString ";
NSString *resultString;
resultString = [self removeEndSpaceFrom:oneTwoThree];
resultString
will then have no spaces at the end.
On my Mobo (ASRock A320M-HD with Ryzen 3 2200G) I have to:

On the OS enable Hyper V.
A possible workaround for the page title:
document.title = "Print page title"; window.print();
This should work in every browser.
You need to loop over loadDT.Columns
, like this:
foreach (DataColumn column in loadDT.Columns)
{
Console.Write("Item: ");
Console.Write(column.ColumnName);
Console.Write(" ");
Console.WriteLine(row[column]);
}
You might want to do something like this (if you're in java 5 & up)
Scanner scanner = new Scanner(new File("tall.txt"));
int [] tall = new int [100];
int i = 0;
while(scanner.hasNextInt()){
tall[i++] = scanner.nextInt();
}
There are two BeanUtils.copyProperties(parameter1, parameter2) in Java.
One is
org.apache.commons.beanutils.BeanUtils.copyProperties(Object dest, Object orig)
Another is
org.springframework.beans.BeanUtils.copyProperties(Object source, Object target)
Pay attention to the opposite position of parameters.
You use runas
to launch a program as a specific user:
runas /user:Administrator Example1Server.exe
this will be more efficient:
public static class StringExtension
{
public static string clean(this string s)
{
return new StringBuilder(s)
.Replace("&", "and")
.Replace(",", "")
.Replace(" ", " ")
.Replace(" ", "-")
.Replace("'", "")
.Replace(".", "")
.Replace("eacute;", "é")
.ToString()
.ToLower();
}
}
In System.Web.Mvc.Html ( in System.Web.Mvc.dll ) the begin form is defined like:- Details
BeginForm ( this HtmlHelper htmlHelper, string actionName, string
controllerName, object routeValues, FormMethod method, object htmlAttributes)
Means you should use like this :
Html.BeginForm( string actionName, string controllerName,object routeValues, FormMethod method, object htmlAttributes)
So, it worked in MVC 4
@using (Html.BeginForm(null, null, new { @id = string.Empty }, FormMethod.Post,
new { @id = "signupform" }))
{
<input id="TRAINER_LIST" name="TRAINER_LIST" type="hidden" value="">
<input type="submit" value="Create" id="btnSubmit" />
}
Only use method Convert.ToBase64String
Convert.ToBase64String(inputStream.ToArray());
With the -atime, -ctime, and -mtime switches to find, you can get close to what you want to achieve.
You can get that error if you have an object with the same name as the schema. For example:
create sequence s2;
begin
s2.a;
end;
/
ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored
When you refer to S2.MY_FUNC2
the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2
there is no confusion, so it works.
The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.
It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.
select owner, object_type, object_name
from all_objects
where object_name = 'S2';
The right and standard way to do it is using classList
. It is now widely supported in the latest version of most modern browsers:
ELEMENT.classList.remove("CLASS_NAME");
remove.onclick = () => {_x000D_
const el = document.querySelector('#el');_x000D_
if (el.classList.contains("red")) {_x000D_
el.classList.remove("red");_x000D_
_x000D_
}_x000D_
}
_x000D_
.red {_x000D_
background: red_x000D_
}
_x000D_
<div id='el' class="red"> Test</div>_x000D_
<button id='remove'>Remove Class</button>
_x000D_

Escaping characters is different for tags and attributes.
For tags:
< <
> > (only for compatibility, read below)
& &
For attributes:
" "
' '
From Character Data and Markup:
The ampersand character (&) and the left angle bracket (<) must not appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they must be escaped using either numeric character references or the strings " & " and " < " respectively. The right angle bracket (>) may be represented using the string " > ", and must, for compatibility, be escaped using either " > " or a character reference when it appears in the string " ]]> " in content, when that string is not marking the end of a CDATA section.
To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as " ' ", and the double-quote character (") as " " ".
In addition to the "raw" tools provided by MutationObserver
API, there exist "convenience" libraries to work with DOM mutations.
Consider: MutationObserver represents each DOM change in terms of subtrees. So if you're, for instance, waiting for a certain element to be inserted, it may be deep inside the children of mutations.mutation[i].addedNodes[j]
.
Another problem is when your own code, in reaction to mutations, changes DOM - you often want to filter it out.
A good convenience library that solves such problems is mutation-summary
(disclaimer: I'm not the author, just a satisfied user), which enables you to specify queries of what you're interested in, and get exactly that.
Basic usage example from the docs:
var observer = new MutationSummary({
callback: updateWidgets,
queries: [{
element: '[data-widget]'
}]
});
function updateWidgets(summaries) {
var widgetSummary = summaries[0];
widgetSummary.added.forEach(buildNewWidget);
widgetSummary.removed.forEach(cleanupExistingWidget);
}
Edit:
In newer Android Studio versions you can re-sync the project using this button:
For older versions:
Open Gradle window (on the right side in Android Studio) and click on the refresh button.
However it is not a 100% sure fix.
Solutions for other cases:
Open terminal window and type "adb kill-server", then type "adb start-server". Usually after a few hours of inactivity, adb used to disconnect the device. (If you don't have the sdk/platform-tools in the PATH environment variable, then you should open a terminal in that folder)
One tip if these solutions don't help you: If you open the Event Log window in the right bottom corner of Android Studio, you can see a detailed error message.
Other edge case If you see this error: INSTALL_FAILED_INVALID_APK:... signatures are inconsistent. Then unfortunately a gradle refresh isn't enough, you have to go to Build -> Clean Project and then Run again.
Issue with Android emulator If you want to deploy the APK to an Android Emulator and you see the "Error installing APK" message, your emulator may be frozen and need restart.
Another difference between them is the size of the file:
To see the performance benefits of Handlebars.js we must use precompiled templates.
Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable
to true) on all brokers first.
Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable
is by default true
.
Follow this step by step process for manual deletion of topics

Compare document.activeElement
with the element you want to check for focus. If they are the same, the element is focused; otherwise, it isn't.
// dummy element
var dummyEl = document.getElementById('myID');
// check for focus
var isFocused = (document.activeElement === dummyEl);
hasFocus
is part of the document
; there's no such method for DOM elements.
Also, document.getElementById
doesn't use a #
at the beginning of myID
. Change this:
var dummyEl = document.getElementById('#myID');
to this:
var dummyEl = document.getElementById('myID');
If you'd like to use a CSS query instead you can use querySelector
(and querySelectorAll
).
$num = array (0 => array ('id' => '20110209172713', 'Date' => '2011-02-09', 'Weight' => '200'),
1 => array ('id' => '20110209172747', 'Date' => '2011-02-09', 'Weight' => '180'),
2 => array ('id' => '20110209172827', 'Date' => '2011-02-09', 'Weight' => '175'),
3 => array ('id' => '20110211204433', 'Date' => '2011-02-11', 'Weight' => '195'));
foreach($num as $key => $val)
{
$weight[] = $val['Weight'];
}
echo max($weight);
echo min($weight);
Why it can be good to store pictures in the database an not in a catalog on the web server.
You have made an application with lots of pictures stored in a folder on the server, that the client has used for years.
Now they come to you. They server has been destroyed and they need to restore it on a new server. They have no access to the old server anymore. The only backup they have is the database backup.
You have of course the source and can simple deploy it to the new server, install SqlServer and restore the database. But now all the pictures are gone.
If you have saved the pictures in SqlServer everything will work as before.
Just my 2 cents.
Just the same way as you would do in command console. Copy exactly those commands in the batch file.

Yes, you can do this by creating a DoubleStream
from the array, filtering out the negatives, and converting the stream back to an array. Here is an example:
double[] d = {8, 7, -6, 5, -4};
d = Arrays.stream(d).filter(x -> x > 0).toArray();
//d => [8, 7, 5]
If you want to filter a reference array that is not an Object[]
you will need to use the toArray
method which takes an IntFunction
to get an array of the original type as the result:
String[] a = { "s", "", "1", "", "" };
a = Arrays.stream(a).filter(s -> !s.isEmpty()).toArray(String[]::new);
In stall PuTTY in our system and set the environment variable PATH Pointing to putty path. open the command prompt and move to putty folder. Using PSCP command
$dateValue = '2012-01-05';
$yeararray = explode("-", $dateValue);
echo "Year : ". $yeararray[0];
echo "Month : ". date( 'F', mktime(0, 0, 0, $yeararray[1]));
Usiong explode() this can be done.
This worked for me:
Select
dateadd(S, [unixtime], '1970-01-01')
From [Table]
In case any one wonders why 1970-01-01, This is called Epoch time.
Below is a quote from Wikipedia:
The number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970,[1][note 1] not counting leap seconds.
You did everything correctly!
You might also change the email configuration, depending on if the email server is also the same server. The email configuration is in gitlab.yml for the mails sent by GitLab and also the admin-email.
Try the following code:
SELECT *
FROM users
WHERE firstname IN ('joe','jane');
get radio value by name
$('input').on('className', function(event){
console.log($(this).attr('name'));
if($(this).attr('name') == "worker")
{
resetAll();
}
});
As explained in here: https://css-tricks.com/centering-in-the-unknown/.
As tested in the real practice, the most reliable yet elegant solution is to insert an assistent inline element into the
<li />
element as the 1st child, which height should be set to 100% (of its parent’s height, the<li />
), and itsvertical-align
set to middle. To achieve this, you can put a<span />
, but the most convenient way is to useli:after
pseudo class.
Screenshot:
ul.menu-horizontal {
list-style-type: none;
margin: 0;
padding: 0;
display: inline-block;
vertical-align: middle;
}
ul.menu-horizontal:after {
content: '';
clear: both;
float: none;
display: block;
}
ul.menu-horizontal li {
padding: 5px 10px;
box-sizing: border-box;
height: 100%;
cursor: pointer;
display: inline-block;
vertical-align: middle;
float: left;
}
/* The magic happens here! */
ul.menu-horizontal li:before {
content: '';
display: inline;
height: 100%;
vertical-align: middle;
}
Using dlpyr::mutate
and forcats::fct_recode
:
library(dplyr)
library(forcats)
iris <- iris %>%
mutate(Species = fct_recode(Species,
"Virginica" = "virginica",
"Versicolor" = "versicolor"
))
iris %>%
count(Species)
# A tibble: 3 x 2
Species n
<fctr> <int>
1 setosa 50
2 Versicolor 50
3 Virginica 50
Maybe too late but I had the same need so I've published this https://github.com/liltof/font-awsome-for-android It's an android ready xml version of font awesome usable just like Keith Corwin said
Hope it will help others.
When you write a lambda expression, the argument list to the left of ->
can be either a parenthesized argument list (possibly empty), or a single identifier without any parentheses. But in the second form, the identifier cannot be declared with a type name. Thus:
this.stops.stream().filter(Stop s-> s.getStation().getName().equals(name));
is incorrect syntax; but
this.stops.stream().filter((Stop s)-> s.getStation().getName().equals(name));
is correct. Or:
this.stops.stream().filter(s -> s.getStation().getName().equals(name));
is also correct if the compiler has enough information to figure out the types.
You probably can use the file system itself as a hash table. Pseudo-code as follows:
for every entry in the ip address file; do
let addr denote the ip address;
if file "addr" does not exist; then
create file "addr";
write a number "0" in the file;
else
read the number from "addr";
increase the number by 1 and write it back;
fi
done
In the end, all you need to do is to traverse all the files and print the file names and numbers in them. Alternatively, instead of keeping a count, you could append a space or a newline each time to the file, and in the end just look at the file size in bytes.
If youR data was in A1:C100
then:
Excel - all versions
=SUMPRODUCT(--(A1:A100="M"),--(C1:C100="Yes"))
Excel - 2007 onwards
=COUNTIFS(A1:A100,"M",C1:C100,"Yes")
I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important
property.
HTML
<a href="#" class="selected_btn" data-role="button">Button name</a>
CSS
.selected_btn
{
border:1px solid red;
text-decoration:none;
font-family:helvetica;
color:red !important;
background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}
Here is the demo
You can do it with dynamic query, just run the following script in pl-sql or sqlplus:
select 'grant select on user_name_owner.'||table_name|| 'to user_name1 ;' from dba_tables t where t.owner='user_name_owner'
and then execute result.
A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib
to include all the .jar files in that directory, it won't. You have to name them explicitly.
Storing files in your database will lead to a huge database size. You may not like that, for development, testing, backups, etc.
Instead, you'd use FileStream (SQL-Server) or BFILE (Oracle).
There is no default-implementation of BFILE/FileStream in Postgres, but you can add it: https://github.com/darold/external_file
And further information (in french) can be obtained here:
http://blog.dalibo.com/2015/01/26/Extension_BFILE_pour_PostgreSQL.html
To answer the acual question:
Apart from bytea
, for really large files, you can use LOBS:

I achieve this in a view with a subview that is an UIImageView. The image the ImageView is pointing to is a gradient. Then I set a background color in the UIView, and I have a colored gradient view. Next I use the view as I need to and everything I draw will be under this gradient view. By adding a second view on top of the ImageView, you can have some options whether your drawing will be below or above the gradient...
Have a think about wrapping the videos inside something which you can make flexible via bootsrap.
The bootstrap is not a magic tool, its just a layout engine. You almost have it in your example.
Just use the grid provided by bootstrap and remove strict sizing's on the iframe. Use the bootstrap class guides for the grid..
For example:
<iframe class="col-lg-2 col-md-6 col-sm-12 col-xs-12">
You will see how the class of the iframe will change then given your resolution.
A Fiddel too : http://jsfiddle.net/RsSAT/
element instanceof RenderedWebElement
should work.
No one here mentioned the built in solution of the emulator itself, so for future visitors, I'd like to share it with visuals.
First, run your Android Emulator and click on the menu button (3 dots) shown below:
Then from the left pane, select Location and change the coordinates according to your needs. After pressing Send button, changes will immediately take effect (I recommend you to open up Google Maps for better understanding).
Android Studio Version: 2.3.3
In addition, to make your different locations coming to your application in real time, you can use GPX file. It's very easy to create this file from Google Map direction link:
Use "Load GPS/KML" button to load the created file to your emulator, choose speed, and press green play button on the bottom. Locations will be sent in real time as shown on the picture below.
I reworked the example you provided in the js fiddle : http://jsfiddle.net/zravs3hp/
I renamed your container
div to overlay
, as semantically this div is not a container, but an overlay. I also placed the loader div as a child of this overlay div.
The resulting html is :
<div class="overlay">
<div id="loading-img"></div>
</div>
<div class="content">
<div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ea velit provident sint aliquid eos omnis aperiam officia architecto error incidunt nemo obcaecati adipisci doloremque dicta neque placeat natus beatae cupiditate minima ipsam quaerat explicabo non reiciendis qui sit. ...</div>
<button id="button">Submit</button>
</div>
The css of the overlay is the following
.overlay {
background: #e9e9e9; <- I left your 'gray' background
display: none; <- Not displayed by default
position: absolute; <- This and the following properties will
top: 0; make the overlay, the element will expand
right: 0; so as to cover the whole body of the page
bottom: 0;
left: 0;
opacity: 0.5;
}
I added some dummy text so as to have something to overlay.
Then, in the click
handler we just need to show the overlay :
$("#button").click(function () {
$(".overlay").show();
});
types.Values.ToList().IndexOf("one");
Values.ToList() converts your dictionary values into a List of objects. IndexOf("one") searches your new List looking for "one" and returns the Index which would match the index of the Key/Value pair in the dictionary.
This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.
Keep in mind there may be more than one "one" value in your dictionary. And that is the reason there is no "get key" method.
for making uppercase from lowercase to upper just use
"string".upper()
where "string"
is your string that you want to convert uppercase
for this question concern it will like this:
s.upper()
for making lowercase from uppercase string just use
"string".lower()
where "string"
is your string that you want to convert lowercase
for this question concern it will like this:
s.lower()
If you want to make your whole string variable use
s="sadf"
# sadf
s=s.upper()
# SADF
If you are only concerned with the constant True
, a simple sum
is fine. However, keep in mind that in Python other values evaluate as True
as well. A more robust solution would be to use the bool
builtin:
>>> l = [1, 2, True, False]
>>> sum(bool(x) for x in l)
3
UPDATE: Here's another similarly robust solution that has the advantage of being more transparent:
>>> sum(1 for x in l if x)
3
P.S. Python trivia: True
could be true without being 1. Warning: do not try this at work!
>>> True = 2
>>> if True: print('true')
...
true
>>> l = [True, True, False, True]
>>> sum(l)
6
>>> sum(bool(x) for x in l)
3
>>> sum(1 for x in l if x)
3
Much more evil:
True = False
strong: assigns the incoming value to it, it will retain the incoming value and release the existing value of the instance variable
weak: will assign the incoming value to it without retaining it.
So the basic difference is the retaining of the new variable. Generaly you want to retain it but there are situations where you don't want to have it otherwise you will get a retain cycle and can not free the memory the objects. Eg. obj1 retains obj2 and obj2 retains obj1. To solve this kind of situation you use weak references.
You can simply return a ResponseEntity with the appropriate header:
@RequestMapping(value = "/updateSomeData" method = RequestMethod.POST)
public ResponseEntity updateDataThatDoesntRequireClientToBeNotified(...){
....
return new ResponseEntity(HttpStatus.OK)
}
This is bit tricky
Now a days most of website new techniques to save websites from scraping
1st Technique
Ctrl+U this will show you Page Source
2nd Technique
This one is small hack if the website has ajax like functionality.
Just Hover the mouse key on inspect element untill whole screen becomes just right click then and copy element
That's it you are good to go.
Does the IIS/IWAM user have permissions on the Oracle directory? Can you connect to this data source using another app, such as Excel or Access?
I know my case is rare, but I'll still add it here for someone who troubleshoots it later. I had a Linux Kernel module target in my Makefile and I tried to compile my user space program together with the kernel module that doesn't have stdio. Making it a separate target solved the problem.
I'd rather use a single instance of a method Delegate instead of creating a new instance every time. In my case i used to show progress and (info/error) messages from a Backroundworker copying and casting large data from a sql instance. Everywhile after about 70000 progress and message calls my form stopped working and showing new messages. This didn't occure when i started using a single global instance delegate.
delegate void ShowMessageCallback(string message);
private void Form1_Load(object sender, EventArgs e)
{
ShowMessageCallback showMessageDelegate = new ShowMessageCallback(ShowMessage);
}
private void ShowMessage(string message)
{
if (this.InvokeRequired)
this.Invoke(showMessageDelegate, message);
else
labelMessage.Text = message;
}
void Message_OnMessage(object sender, Utilities.Message.MessageEventArgs e)
{
ShowMessage(e.Message);
}
function myFunction(arg) {
alert(arg.var1 + ' ' + arg.var2 + ' ' + arg.var3);
}
myFunction ({ var1: "Option 1", var2: "Option 2", var3: "Option 3" });
I use MacTex, and my editor is TexShop. It probably has to do with what compiler you are using. When I use pdftex, the command:
\includegraphics[height=60mm, width=100mm]{number2.png}
works fine, but when I use "Tex and Ghostscript", I get the same error as you, about not being able to get the size information. Use pdftex.
Incidentally, you can change this in TexShop from the "Typeset" menu.
Hope this helps.
You could use a setter for @ViewChild()
@ViewChild(FilterTiles) set ft(tiles: FilterTiles) {
console.log(tiles);
};
If you have an ngIf wrapper, the setter will be called with undefined, and then again with a reference once ngIf allows it to render.
My issue was something else though. I had not included the module containing my "FilterTiles" in my app.modules. The template didn't throw an error but the reference was always undefined.
I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.
Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...
Now, this one is quite tricky, but works well if most simple 1px hr needed:
Variation 1, BLACK hr: (best solution for black)
<hr style="border-bottom: 0px">
Output: FF, Opera - black / Safari - dark gray
Variation 2, GRAY hr (shortest!):
<hr style="border-top: 0px">
Output: Opera - dark gray / FF - gray / Safari - light gray
<hr style="border: none; border-bottom: 1px solid red;">
Output: Opera / FF / Safari : 1px red.
There's no need to use a lib specific API if you use python-benedict
. Just initialize a new instance from your XML and manage it easily since it is a dict
subclass.
Installation is easy: pip install python-benedict
from benedict import benedict as bdict
# data-source can be an url, a filepath or data-string (as in this example)
data_source = """
<foo>
<bar>
<type foobar="1"/>
<type foobar="2"/>
</bar>
</foo>"""
data = bdict.from_xml(data_source)
t_list = data['foo.bar'] # yes, keypath supported
for t in t_list:
print(t['@foobar'])
It supports and normalizes I/O operations with many formats: Base64
, CSV
, JSON
, TOML
, XML
, YAML
and query-string
.
It is well tested and open-source on GitHub. Disclosure: I am the author.
You can get entire post body into a POJO. Following is something similar
@RequestMapping(
value = { "/api/pojo/edit" },
method = RequestMethod.POST,
produces = "application/json",
consumes = ["application/json"])
@ResponseBody
public Boolean editWinner( @RequestBody Pojo pojo) {
Where each field in Pojo (Including getter/setters) should match the Json request object that the controller receives..
You can also try this code without floats (faster but less accurate):
typedef struct RgbColor
{
unsigned char r;
unsigned char g;
unsigned char b;
} RgbColor;
typedef struct HsvColor
{
unsigned char h;
unsigned char s;
unsigned char v;
} HsvColor;
RgbColor HsvToRgb(HsvColor hsv)
{
RgbColor rgb;
unsigned char region, remainder, p, q, t;
if (hsv.s == 0)
{
rgb.r = hsv.v;
rgb.g = hsv.v;
rgb.b = hsv.v;
return rgb;
}
region = hsv.h / 43;
remainder = (hsv.h - (region * 43)) * 6;
p = (hsv.v * (255 - hsv.s)) >> 8;
q = (hsv.v * (255 - ((hsv.s * remainder) >> 8))) >> 8;
t = (hsv.v * (255 - ((hsv.s * (255 - remainder)) >> 8))) >> 8;
switch (region)
{
case 0:
rgb.r = hsv.v; rgb.g = t; rgb.b = p;
break;
case 1:
rgb.r = q; rgb.g = hsv.v; rgb.b = p;
break;
case 2:
rgb.r = p; rgb.g = hsv.v; rgb.b = t;
break;
case 3:
rgb.r = p; rgb.g = q; rgb.b = hsv.v;
break;
case 4:
rgb.r = t; rgb.g = p; rgb.b = hsv.v;
break;
default:
rgb.r = hsv.v; rgb.g = p; rgb.b = q;
break;
}
return rgb;
}
HsvColor RgbToHsv(RgbColor rgb)
{
HsvColor hsv;
unsigned char rgbMin, rgbMax;
rgbMin = rgb.r < rgb.g ? (rgb.r < rgb.b ? rgb.r : rgb.b) : (rgb.g < rgb.b ? rgb.g : rgb.b);
rgbMax = rgb.r > rgb.g ? (rgb.r > rgb.b ? rgb.r : rgb.b) : (rgb.g > rgb.b ? rgb.g : rgb.b);
hsv.v = rgbMax;
if (hsv.v == 0)
{
hsv.h = 0;
hsv.s = 0;
return hsv;
}
hsv.s = 255 * long(rgbMax - rgbMin) / hsv.v;
if (hsv.s == 0)
{
hsv.h = 0;
return hsv;
}
if (rgbMax == rgb.r)
hsv.h = 0 + 43 * (rgb.g - rgb.b) / (rgbMax - rgbMin);
else if (rgbMax == rgb.g)
hsv.h = 85 + 43 * (rgb.b - rgb.r) / (rgbMax - rgbMin);
else
hsv.h = 171 + 43 * (rgb.r - rgb.g) / (rgbMax - rgbMin);
return hsv;
}
Note that this algorithm uses 0-255
as it's range (not 0-360
) as that was requested by the author of this question.
